The size of the reward has gone up ninefold in recent days and is likely headed higher, the blog adds. Donations have been coming in from around the nation.

As Crime Time reports, "Lightning Medicine Cloud and his mother, Buffalo Woman, were killed just shy of the white buffalo's first birthday. Arby Little Soldier, great-great-great grandson of Sitting Bull and owner/operator of the Lakota Ranch, said Monday that he found the calf slaughtered and skinned April 30 after returning to the North Texas town from an out-of-town trip to Oklahoma City." Buffalo Woman died a day later. Little Soldier suspects she was poisoned.

On the ranch's website, there's a post that explains the significance of a white buffalo to Native Americans. It says, in part, that:

"The Native Americans see the birth of a white buffalo calf as the most significant of prophetic signs, equivalent to the weeping statues, bleeding icons, and crosses of light that are becoming prevalent within the Christian churches today. Where the Christian faithful who visit these signs see them as a renewal of God's ongoing relationship with humanity, so do the Native Americans see the white buffalo calf as the sign to begin life's sacred hoop."

Our colleagues at KETR-FM say this weekend's Native American Powwow at the ranch was supposed to be "a ceremony honoring the birth of a sacred white buffalo." Instead, it will "serve as a memorial for Lightning Medicine Cloud" and his mother.
